Abstract

PURPOSE:To prevent the strain after forming and the strain with the elapse of time, by keeping the periphery of a thin disk by the composite force of compression and welding, and forming a diaphragm by pressure. CONSTITUTION:A disk, whose diameter is equal to the inner diameter of a circular recess part 3 in a flange 2, is blanked from a diaphragm material 1. The material 1 is coupled with the recess part 3, and compressed and temporarily set to the recess part 3 by a ring 4 having the same diameter. Concentric circular waveforms 5, 5... are formed on the surface of the bottom of the recess part 3. A pressure transmitting hole 6 is formed at the central part of the recess part 3. Under the state the diaphragm material 1 held by the flange 2, the ring 4 is tightened by a compressing and tightening tool and welded to concentric welding lines 7 and 8. Sealing is performed by a compressing lid 9 of the flange 2 through a packing 10, and hydraulic pressure is applied to make waveforms on the diaphragm.

不安定で、３００％４ｚ。[Detailed Description of the Invention] To detect minute pressures, it is either necessary to use a diaphragm, or conventionally, the peripheral edge of the tire flam is welded directly to the flange using beam welding or the like. In this method, the heat effect at the welding point is unstable, causing distortion in the tire flam, and is 300% 4z.

The present invention uses a combined force of crimping and welding to hold the peripheral edge of a thin disk and pressure-form the diaphragm, thereby avoiding the method of welding a formed diaphragm. The diaphragm material 1 is punched out into a circular shape having the same inner diameter as the circular recess 3 inside the flange 2, and this is inserted into the recess 31 and then temporarily set in the recess 3 by pressure bonding with a link 4 having the same diameter. Concentric corrugations 5, 5, . Now, the ring 4 is inserted between the flange 2 and the diaphragm material 1, and is firmly tightened with a crimp cotton fitting.
After sealing through the diaphragm 1 and applying hydraulic pressure, the diaphragm 1 is formed along the corrugations 55 on the back surface.

Because of the molding method, there is no distortion after molding or distortion over time (and the corrugations on the back always provide support for close contact, making this method significantly different from other one-shot diaphragm welding methods).

法。When welding a tire plum to a flange as a pressure sensor, we cut concentric waveforms on the bottom of the flange, insert a punched diaphragm material into the inner diameter of the flange recess, temporarily attach it, and attach a ring of the same diameter to its periphery. At the flat part, we beam-welded the upper and lower concentric circles with the main crimping, then covered them with a pressure lid, tightened them, shaped them to follow the waveform, and then beam-welded them on the concentric lines. Diaphragm manufacturing method.
